Preamble: Eggs from Syncuaria squamata recovered by Wong & Anderson (1987) from Lake Ontarian cormorants were fed to ostracods. Granulomata containing L3 were found on the intestinal serosa of domestic goldfish Carassius auratus fed infected ostracods. Adult worms were recovered from a cormorant fed infected goldfish alimentary tracts. Although it appears that fish serve as paratenic hosts of S. squamata , no records have been traced of this nematode infecting wild fishes in Canadian waters. Because Wong & Anderson (op. cit.) did not describe the L3 from goldfish the following description is based on the description they provided for L3 from ostracods.

Description (after Wong & Anderson 1987). Pseudolabia well developed with prominent apices. Four interlabia originating at dorso-ventral sides of oral opening, surrounding pseudolabia and terminating at amphids. Four prominent cephalic papillae immediately behind interlabia. Buccal cavity elongated and expanded at oral opening ( Fig. 71 View FIGURE 71 A). Deirids with pointed tips immediately behind excretory pore. Muscular oesophagus about one-fifth length of glandular oesophagus. Genital primordia present in males and females. Rectum elongated and anus patent. Tail with slight dorsal curve and rounded tip ( Fig. 71 View FIGURE 71 B).

Male L3: 1.20 (0.98–1.38) long, 0.049 (0.040–0.058) wide. Excretory pore 0.102 (0.090–0.122) from anterior end. Total oesophagus (muscular plus glandular) 0.612 (0.512–0.712) long. Female L3: 1.14 (1.04–1.38) long, 0.047 (0.040–0.065) wide. Excretory pore 0.098 (0.080–0.105) from anterior end. Total oesophagus (muscular plus glandular) 0.583 (0.485–0.726) long.
